The Economist: The Frayed Knot (2)

I hadn't forgotten about The Frayed Knot series that I had started last month. However, before I move into the next section that I want to discuss, I thought I'd C&P a few paragraphs from the article that I think are interesting but not necessarily comment-worthy:

In her book “Marriage and Caste in America”, [Kay Hymowitz of the Manhattan Institute, a conservative think-tank] argues that the “marriage gap” is the chief source of the country's notorious and widening inequality. Middle-class kids growing up with two biological parents are “socialized for success.” They do better in school, get better jobs and go on to create intact families of their own. Children of single parents or broken families do worse in school, get worse jobs and go on to have children out of wedlock. This makes it more likely that those born near the top or the bottom will stay where they started. America, argues Ms. Hymowitz, is turning into “a nation of separate and unequal families.”

A large majority—92%—of children whose families make more than $75,000 a year live with two parents (including step-parents). At the bottom of the income scale—families earning less than $15,000—only 20% of children live with two parents. One might imagine that this gap arises simply because two breadwinners earn more than one. A single mother would have to be unusually talented and diligent to make as much as $75,000 while also raising children on her own. And it is impossible in America for two full-time, year-round workers to earn less than $15,000 between them, unless they are (illegally) paid less than the minimum wage.

But there is more to it than this. Marriage itself is “a wealth-generating institution”, according to Barbara Dafoe Whitehead and David Popenoe, who run the National Marriage Project at Rutgers University. Those who marry “till death do us part” end up, on average, four times richer than those who never marry. This is partly because marriage provides economies of scale—two can live more cheaply than one—and because the kind of people who make more money—those who work hard, plan for the future and have good interpersonal skills—are more likely to marry and stay married. But it is also because marriage affects the way people behave.

American men, once married, tend to take their responsibilities seriously. Avner Ahituv of the University of Haifa and Robert Lerman of the Urban Institute found that “entering marriage raises hours worked quickly and substantially.” Married men drink less, take fewer drugs and work harder, earning between 10% and 40% more than single men with similar schooling and job histories. And marriage encourages both spouses to save and invest more for the future. Each partner provides the other with a form of insurance against falling sick or losing a job.

Marriage also encourages the division of labor. Ms. Dafoe Whitehead and Mr. Popenoe put it like this: “Working as a couple, individuals can develop those skills in which they excel, leaving others to their partner.” Mum handles the tax returns while Dad fixes the car. Or vice versa. As Adam Smith observed two centuries ago, when you specialize, you get better at what you do, and you produce more.
